1.
notice; announcement; notification
A polite word for a notice, announcement, or piece of information communicated to someone. The honorific prefix お makes it suitable for formal and everyday use.
Ubiquitous in daily life — seen on websites, in emails, on signs, and in apps. Common patterns include ~のお知らせ (notice about ~) and お知らせいたします (we would like to inform you). Without the お prefix, 知らせ is a plain noun meaning news or information. The phrase 嬉しいお知らせ (happy news) and 悲しいお知らせ (sad news) are set expressions for delivering good or bad news.
